       The only scenario of this type is the World.scn. I'm still working on that.

       (I'll try to finish that soon.)
    Type 4 = Single map that wraps side to side.
         (highest map column is adjacent to lowest map column)
         Exit right edge, enters left edge.

.ppt files
Prestige or Production per turn.
These files are for Bonus Prestige or Production. 
The filename is the same as the scenario name. The extension is .ppt
Turn, Nation Number, Amount
On that turn, that nation will receive that amount of prestige or production.
If using production rules the Nation will receive the points.
If using Prestige the side that nation is on will receive the points as prestige.
UK01.scn has a sample of this file.

.pol
Political Modifier files. Not used for Scenario type 0.
filename is the same as the scenario name, the extension is .pol
This is an optional file for scenarios. It contains the modifiers to the
Declarations of War, Alliance checks. 
These used to be text files, but they were hard to edit. So, I changed them
and wrote an editor for them. editpol.exe.
See editpol.txt for more details.
